Without sounding a nutter or a conspiracy theorist, I think there are a lot of very complex issues at play here.
With all the trillions of dollars of money that is generated from fossil fuels, the companies/governments that own these assets, will want to maximise revenues from these, before they become uneconomic to plunder. In the meantime consumers will be faced with having to spend an increasing proportion of their income on their energy needs. To avoid this, consumers should be investing in energy efficient measures/products to keep their usage as low as possible.
Once the current fossil fuels become uneconomic or outdated in about 25 years time due to cost and environmental issues, you will start to see new technology being introduced that will make energy a lot cheaper. But only cheaper by the level of costs in 25 years time.
If government wanted to help industry bring new technology to the market within say the next 10 years, why are they not investing more money in R&D. Could it be that they do not wish to upset the oil rich nations that have bought some of the government debts and own businesses/assets here ?
